When the SoeMac is switched on, the molecules inside of the photo-sensitiser become excited, and when the airborne oxygen passes across their surfaces, the excitation energy is passed to the oxygen molecules, briefly changing their molecular structure from their usual stable state, to a singlet state, known as Singlet Oxygen Energy, or SOE. These oxygen molecules immediately revert to their normal passive state, but retain this extra energy in their molecular bonds.
It is this extra energy, combined with the oxygen molecules, that is so welcomed by the body.
